Simplify the expression and then evaluate it for the given value of the variable:

Natasha_Volkova [10]

Answer:

-5x+21
22

Step-by-step explanation:

There are no factors outside the parentheses that need to be distributed, so the parentheses can be simply dropped:

6 -2x +15 -3x

The terms can be rearranged to put like terms next to each other:

-2x -3x +6 +15

and the like terms can be combined.

-5x +21 . . . . simplified expression

Put the value of x where x is, then do the arithmetic.

-5(-0.2) +21 = 1 +21 = 22

Solve the two-step equation. -9x + 0.4 = 4 Which operation must be performed to move all the constants to the right side of the

Alexandra [31]

Answer:

x = -0.4

Step-by-step explanation:

We have the equation:

-9x + 0.4 = 4

First, the operation to move all the constants to the right side is subtraction since we would have to subtract 0.4 from each side, let's see this:

$-9x+0.4=4\\-9x+0.4-0.4=4-0.4\\-9x=3.6$

Now, we have all the constants on the right side of the equation.

Now, the operation we need to perform to isolate the variable is division (since the x has a -9 that is being multiplied by x) we need to do the opposite operation:

$-9x=3.6\\\frac{-9x}{-9} =\frac{3.6}{-9} \\x=-0.4$

<h3>Thus, the answer to this equation is x= -0.4</h3>
